The locker for your sea time.

SeaTime is built for Ordinary Seamen, Able Seamen, and other mariners working toward an MMC raise in grade. Log voyages on the boat, snap old letters, and keep papers in one place — even when the ship has no signal.

What you can do

• Log sea days and watch hours by vessel, official number, and rating
• Track MMC, medical, TWIC, STCW, and drug-test windows
• Digitize old sea service letters and discharges from photos
• Scan QR and barcode labels on certs and gangway codes
• Build a Coast Guard-friendly sea service letter
• Keep a photo locker of MMC, TWIC, and discharges on this device
